TOY SUBMARIN'E.

Specification of Letters Patent.

Patented 001;. 19, 1920.

Application filed February 14, 1920. Serial No. 558,690.

To all whom it may concern:

Be it known that I, ROY E. LUNDsTROM, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Toy Submarine, of which the following is a specification.

My invention relates to toys and the ob ject is to provide a toy resembling and operated like a submarine boat.

In the accompanying drawing:

Figure l is a top or plan view of the toy. Fig. 2 is a side view of it showing it ready to dive in the water.

Referring to the drawing by reference numerals, 3 designates the body of the submarine which may be made of any suitable material but in a cheap toy wood will be good enough. Said body is a kindof cocoon shape tapering to both ends and may have an imitation conning tower l and periscope 5 upon its front half while the rear portion is provided with two opposite lateral, normally horizontal wings 6 and also a vertical rudder 7. The latter may preferably consist of two parallel blades cut and formed integral with the sheet metal I forming the Wings 6.

Near'the middle the body 3 is provided with a vertical cylindrical chamber 8, the bottom of which is normally closed by a skeletoned or perforated lid 9, hinged at 10 and having its rear edge normally sup ported. by catch 11 on a lever 12. Said lever is pivoted at 13 and is suspended down which it has freedom to swing sufliciently rearward to release the lid 9.

In the operation of the toy it is placed upon the water in a wash tub, bath tub or pond or other Water where it floats in about the position shown in Fig 2. A marble 15 or other stone or pebble, or gravel or coarse sand is then deposited in the chamber 8. The deposited weight causes the toy to through an inverted pocket 14 in sink, and as the wings retard the sinking of the rear end of the boat, the boat assumes an incline and glides on its wings 6 forward and downward until the lower end of the lever 12 touches the bottom of the water and is thereby disengaged from the lid 9, whereupon said lid falls downward and lets the marble or stone l5 escape.

The boat being thus released of its ballast or sinker 15 it floats to the surface again, not directly upward but also with a forward movement, caused by the now reversed inclined position of the wings 6, they being partly retarded by the water so that the frontend of the boat rises faster than the rear end.

If the water is shallow the same marble or stone may be broughtup and used over and over again and in deep water the chea ballast or sinker is considered lost and the playing child simply finds other pebbles or gravel for the next drive.

What I claim is:

In a submarine toy, both ends and having near its middle a vertical bore extending through it, a plate hinged with its front edge near the front edgeof the bottom end of the bore and arranged to support a weight in the bore for sinking the toy, a vertically disposed trigger or trip lever pivotally suspended in a cavity near the rear edge of the plate and having a catch by which to normally engage said rear edge and support the plate and the weight; said lever depending some distance below the plate and adapted to trip the plate as soon as the lower end of a body tapered to the lever contacts with the bottom of the water during the forward movement of the toy; and means for causing the toy to in? cline with its front end downwardly during the descent and upwardly during the ascent of the toy.

In testimony whereof I afiix my signature. ROY E. LUNDSTROM.
